MEANS FOR GAGING- OR MEASURING TILES.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed April 29, 1911. Serial No. 624,096.

To all whom it may concern:

Be it known that I, HARRY JOHNSON, subject,of the King of Great Britainand Ireland, and resident of Newcastle-under- Lyme, in the county ofStafford, England, tile manufacturer, have invented certain new anduseful Improved Means for Gaging or Measuring Tiles, of which thefollowing is a specification.

My invention relates to means employed for measuring tiles during thecourse of manufacture so as to enable them to be sorted out and eachsize assembled together. This is rendered necessary since during themanufacture of the tiles the contraction of the material of which theyare composed varies according to the temperature at which they are firedso that an ordinary, say, six inch tile may vary considerably, thedifference in size either above or below the standard measurement may be2-; of an inch or more.

Prior to the date of my invention tiles have been sized into variouslots by being matched with standard sizes of tiles or with standardsizes of gages each varying to the extent of of an inch. This is a slowprocess and at the same time is not eflicient since it depends upon thejudgment of the person sizing the tiles as to whether he actually sortsthem out properly. Mechanical devices have also been employed for thesame purpose as my invention which is designed to produce a differentmechanical arrangement to that already employed and one which willobviate all the disadvantages of the gaging process previously referredto.

My invention will be fully described with reference to the accompanyingdrawings in which,

Figure 1 is a front elevation of a device constructed in accordance withmy invention in which the tile is not present while Fig. 2 is a similarview showing the actual measurement of a tile.

In accordance with my invention I employ a base a or frame of anysuitable size, having at one side a raised rib 1) against which one edgeof the tile can be placed. The other side of the base is provided with apivoted finger or pointer 0, mounted on a stud (Z secured to the base.The pointer has mounted on it a knife-edged disk 0. Any

other approved form of gage member besides the disk 6 may be used. I,however, usually employ a knife-edged disk the extreme ridge of whichenables a more accurate measurement to be obtained than would be thecase were the edge of the disk parallel with the axis of the pointer,though I would have it understood that a disk with such an edge, or witha more or less rounded edge, may be employed. In the case of any of theforms of disks referred to being employed they may be mounted loosely onthe pointer so that they may turn around freely and cause equal wear ofthe edge all around but otherwise they are a close fit on the finger orpointer. The extreme end ofthe latter is arranged to operate in front ofa stationary graduated scale f so that when a. tile 9, as in Fig. 2, isplaced on the base a and pushed against the raised rib b it can bemeasured by pushing the wheel or disk 6 against the outer edge h of thetile when the pointer will indicate on the scale f the classification towhich the tile belongs.

I may employ in conjunction with the pointer 0 means for turning it andits disk or projection normally in the direction of the tile on thebase. Such means may consist in a weighted cord z passing over a pulleyj one end of the cord being connected to the pivoted portion of thepointer while the other end is coupled to a suitable weight 70. Or theboss of the pointer, or the pointer arm, may be coupled to a springadapted to act in the direction previously referred to. Projections mmay be arranged on the frame of the device to limit the movement of thepoint in either direction.

From the foregoing description it will be understood that the essentialfeature of my invention consists in the use of a pivoted movable pointeroperating in conjunction with a graduated scale marked to indicate thevarious sizes of tiles.

What I claim as my invention and desire to secure by Letters Patent is Agaging machine for tiles, comprising a frame having at its lower part asupport for the tiles to rest on, a stationary gage member projectingabove the said support at one side thereof, a pointer pivoted to thelower part of the frame on the other side of the said support andprojecting upwardly and adapted to be grasped by the hand, a the tile isbeing placed in position or being gage member earned by the saidpointer, removed from the said support. 10 .a scale on the upper part ofthe frame ad- In testimony whereof I have hereunto set jacent to thefree end of the pointer, and my hand in the presence of two witnesses.means for moving the pointer automatically HARRY JOHNSON. toward theedge of a tile placed on the sup- Witnesses:
